SIDE FRAME FOR CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent N 0. 785,790, dated March 28, 1905.

' Application filed June 22, 1904. Serial No. 213,661.

1'0 (bi/L w/wm it may concern.-

Be it known that I, WILLIAMP. BETTENDORF, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Side Frames for Car- Trucks, of which the following is a full, clear, and exact description.

The object of my invention is to so construct the side frames of the common freight-car truck that by a simple modification of its parts the truck-bolster can be removed from between the guide-columns thereof without its being necessary to dismantle and knock down the entire side fram and thus permit of the parts of the side frame being connected by rivets and dispense with the cost of numerous bolts. nuts, and cotters and the labor of assembling the same and avoid the danger arising from the lower projecting ends of the bolts both to the ties and to the car when a wheel or an axle breaks and the side frames slide on the ground. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure l is a plan view of a side frame for a car-truck embodying my invention. Fig. 2 is a side View thereof. Fig. 3 is a transverse vertical section taken on dotted line 3 3, Fig. 2, looking in the direction indicated by the arrows. Fig. 4 is a view similar to Fig. 3, showing my invention used in connection with a spring-plank. Fig. 5 is a side view of the central portion of a side frame constructed as shown in Fig. 4 and including the bolster and bolster-springs.

The side frame illustrated in the drawings comprises an upper arch-bar A, a lower or in verted arch-bar B, and a tie-bar C, all constructed and arranged in the usual manner. The central portions of the upper and lower arch-bars are connected by the vertical guidecolumns D D in the same manner as the wellknown Master Car-Builders freight-car truck, except, that the bolts a 0, extending longitudinally through said guide-column that fasten the upper and lower arch-bars thereto and the tie-bars in proper position, are headed at each column bolts used in connection with the said Master Car-Builders trucks have one end threaded and are tightened by nuts engaging said threaded portions, so as to permit of their removal and the removal or further separation of the guide-columns when the truckbolster is to be removed.

Secured to the central horizontal portion of theinverted arch-bar between the lower ends of the guide-columns is a removable springseat E, which comprises a platform that preferably projects a suitable distance on each side of the side frame to afford the necessary support for bolster-springs and has parallel downwardly projecting longitudinal flanges Z) I), which when the spring-seat is in proper position lap down on each side of the lower arch-bar and prevent lateral displacement of said seat. If desired, brackets c c 0 may be interposed between the overhanging portions of the spring-seat and flanges 7) I), as shown,

and while it is considered that the weight of.

the springs, the bolster, and the load carried thereby will be suiiicient to keep the springseat in place without the employment of other means, which latter means might be employed for this purpose, if desired. The lower portion of the sides of the guide-columns that face each other and are engaged by the guidebloeks of the bolster are inset or cut away at (2 0, as shown, to an extent sufficient for the bolster and when the springs have been removed out from under the same to be lowered until between the lower farther-separated portions of the guide-column, in which position its guide-block will clear the guide-columns and the bolster can be moved endwise out of the side frame. I prefer to provide the upper surface of the platform of this spring-seat with a groove extending in the same direction as the length of the side frame and transverse to the springplank Gr, that rests thereon. This groove 9 is made in the spring-seat over the lower arch-bar, and the spring-plank is depressed transverselynear its ends to provide a downwardly-projecting tenon lathat enters said groove g. The weight of the bolster K and springs 7t, supporting the end, so as to beimmovable, Whereas the guide- 1 same, rests upon and keeps the spring-plank interlocked with the side frame; but, if de sired, the grooves in the spring-seats and the tenons l? in the spring-planks may be omitted.

The ends of the upper and lower arch-bars lap against each other over the journal-boxes I, which latter may be of any of the standard make, and is secured between the lapping ends of said arch-bars and the ends of the tiebar by vertically-disposed rivets J J, which extend through said bars and have their upper and lower ends headed. The advantage of having the ends, and particularly the lower ends, of these rivets headed is that should the truck or the car-wheels break down the lower headed ends of the rivets present no obstruction to the ties of the road-bed, but slip over the same, and therefore avoid the damage that always results both to the road-bed and the rolling-stock from the use of bolts having nuts and cotters on their lower projecting screwthreaded ends, as is now the case with the common diamond frame now in use.
